Abstract

We investigated the surface physicochemical properties of biomedical materials (made from polylactic acid (PLA), hydroxyapatite (HA), and composites based on PLA and HA with the mass ratio of 80/20 and 60/40, respectively) modified by C+ and Ag2+ ion implantation at the dose of 1 × 1016 cm–2 at the accelerating voltage of 20 kV. It was found that ion implantation leads to greater crystallite size and crystallinity of materials, larger pore volume in surface layers, enhanced surface conductivity, and reduced microhardness of materials.
